Re: G05 tube ground question

The 'aquadag' coating on the outside of the picture tube must be connected
to the monitor chassis common for the tube to charge up correctly...it is
only a giant glass capacitor after all, a few ufd at 20Kv...you can use a
spring if you like, but it must make a good contact to the tube coating and
cover a few square inches. A better solution is to get a piece of braided
wire and run it across the rear of the tube with a spring to keep the braid
from touching the yoke. Then solder a jumper wire that can be either
soldered or screwed to the chassis common.
